WebSound propagation in the ocean is governed by the spatial structure of the sound speed and the sound speed in the ocean is a function of temperature, salinity, and ambient pressure. Since the ambient pressure is a function of depth, it is customary to express the sound speed (c) in meters per second as an empirical function of temperature (T) in … Web26 dec. 2015 · Ultrasound, as the name implies, is high-frequency sound. Sound waves travel through a medium by causing local displacement of particles within the medium; however, there is no overall movement of the medium. Unlike light, sound cannot travel through a vacuum as sound waves need a supporting medium. Consider a piece of …
